What I always find funny about Japan and less harsh winters theory, is its the snowiest country in the world and has 2 of the most snow fall cities (honesty i'm not making it up, its over 40ft a year or something). Seems mad considering how little protection they put on all the MX5's over the years lol.
But aside from that, MOT's are easy to come by if you are in the trade (not implying anything just stating a fact). The underside seems very clean with lots of stickers visible for 60k miles, I was expecting garage queen and 10k based on the underside. and I would be more than cautious, if it seems to good to be true etc. etc.
But i'm glass half empty kind of person.
